Description
[0001] Japanese Patent Application No. 2003-283649, filed on Jul.
31, 2003, is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to a control lever device.
More particularly, the present invention relates to a control lever
device suitable for use as a gearshift lever for a driving game
machine or the like.
[0003] A multi-directional control switch disclosed in Japanese
Patent No. 2740145 has been known as a control lever device used
for a driving game machine or the like.
[0004] This multi-directional control switch includes a lever, a
lever receiving section which supports the lever and allows the
lever to be tilted in a one-axis direction and an other-axis
direction which intersects the one-axis direction, an automatic
return means which automatically returns the tilted lever to the
upright position, a fixing means which secures the lever at a tilt
position in one of the one-axis direction and the other-axis
direction against the returning force applied by the automatic
return means, and a switching means provided corresponding to the
tilt position of the lever.
[0005] In this multi-directional control switch, the lever can be
tilted in the one-axis direction and the other-axis direction by
using the lever receiving section. However, since the lever
receiving section can be returned to the upright position merely by
the automatic return means, a gearshift feeling does not occur
during the lever operation, whereby the operational feeling differs
from the operational feeling of an actual gearshift lever
operation.
[0006] Moreover, since the automatic return means which returns the
tilted lever to the upright position is indispensable, the
structure becomes complicated even in the case where the lever is
tilted only in one direction.
[0007] Furthermore, since the switching means is provided
irrespective of the lever receiving section, it is necessary to
additionally provide a switching means even in the case where the
lever is tilted only in one of the one-axis direction and the
other-axis direction, whereby the degree of generality is
decreased.
BRIEF SUMMARY OF THE INVENTION
[0008] (1) A Control Lever Device According to the Present
Invention Includes:
[0009] a control lever unit which includes an inner frame, a
control lever supported by the inner frame in a manner to be
movable about a fulcrum along a first direction, and a positioning
roller which is attached in the inner frame and allows the control
lever to be positioned at a first displacement position and a
second displacement position located on a straight line by allowing
an end of the control lever to pass over the positioning
roller;
[0010] an outer frame which supports the control lever unit so that
the control lever unit is movable in a second direction which
intersects the first direction at right angles; and
[0011] a moving path control section which controls a moving path
of the control lever,
[0012] wherein the control lever unit includes a lever position
detection section which detects a position of the control lever,
and
[0013] wherein the outer frame includes a unit position detection
section which detects movement of the control lever unit.
[0014] According to the present invention, the control lever unit
is formed so that the control lever can be positioned at the first
displacement position and the second displacement position located
on a straight line by allowing the end of the control lever
supported so as to be able to move about a fulcrum along the first
direction to pass over the positioning roller. Therefore, since the
end of the control lever passes over the positioning roller and is
positioned, a gearshift feeling occurs when shifting the control
lever, whereby an excellent operational feeling can be
obtained.
[0015] Moreover, the first displacement position and the second
displacement position of the control lever can be detected in the
control lever unit by providing the lever position detection
section which detects the position of the control lever for the
control lever unit. Therefore, in the case where the control lever
is provided so as to be able to move about the fulcrum only in the
first direction, the control lever unit can be used without
additionally providing a lever position detection section. This
makes it possible to easily deal with various movement directions
and movement positions of the control lever, whereby the degree of
general-purposeness is increased.
[0016] Furthermore, the control lever can be operated without using
an automatic return means by allowing the control lever unit to be
movable in the second direction which intersects the first
direction at right angles along the moving path control section
which controls the moving path of the control lever, whereby the
structure can be simplified.
[0017] (2) With this control lever device, the control lever unit
may be provided in the outer frame so that the control lever unit
is movable about a fulcrum in the second direction, and may be
biased toward a neutral position by a neutral position biasing
section.
[0018] This configuration enables the control lever to be
automatically returned to a neutral position by the neutral
position biasing section when returning the control lever to a
neutral position.
[0019] (3) With this control lever device, two of the positioning
rollers may be arranged side by side, and the control lever may be
positioned at a neutral position which is between the first and
second displacement positions by positioning the end of the control
lever between the positioning rollers.
[0020] This configuration enables the control lever to be
positioned at the neutral position in addition to the first and
second displacement positions, whereby an excellent operational
feeling can be obtained and a three-stage shift operation can be
easily and securely performed.
[0021] (4) With this control lever device, the moving path control
section may be replaceable so that the moving path of the control
lever changes.
[0022] This configuration enables the control lever to be easily
and securely moved corresponding to various types of moving paths
of the control lever.

DETAILED DESCRIPTION OF THE EMBODIMENT
[0031] An embodiment of the present invention is described below
with reference to the drawings.
[0032] FIGS. 1 to 8 are views showing a control lever device
according to an embodiment of the present invention.
[0033] FIG. 8 is an oblique view showing a driving game machine
using the control lever device according to the present
embodiment.
[0034] A driving game machine 10 is formed so that a player drives
a racing car which runs on a circuit course or a street course, and
competes for ranking and time with a computer car controlled by a
computer or a racing car driven by another player.
[0035] A player plays a game by operating a steering wheel 16 while
seated on a seat 12 and watching a display 14, stepping on an
accelerator pedal 18 or a brake pedal 20 if necessary, and
operating a control lever device 22 which is a gearshift lever.
[0036] FIGS. 1 to 7 show the control lever device 22.
[0037] FIG. 1 is a partial cross-sectional side view of the control
lever device in which a lever position detection section and a unit
position detection section are omitted; FIG. 2 is a plan view of
the control lever device shown in FIG. 1; FIG. 3 is a rear view of
the control lever device shown in FIG. 1 viewed in the direction of
the arrow III; FIGS. 4A and 4B are side views showing the state of
the lever position detection section when a control lever is pushed
forward; FIGS. 5A and 5B are side views showing the state of the
lever position detection section when the control lever is pulled

position detection section when the control lever is moved to the
right.
[0038] As shown in FIGS. 1 to 3, the control lever device 22
includes a control lever unit 24, an outer frame 26, and a moving
path control section 28.
[0039] The control lever unit 24 includes an inner frame 30, a
control lever 32, two positioning rollers 34a and 34b, and two
lever position detection sections 36a and 36b shown in FIGS. 4A,
4B, 5A, and 5B.
[0040] The inner frame 30 is almost in the shape of a rectangular
parallelepiped of which the upper and lower sides are opened.
Support shafts 38a and 38b project outward from opposite side
surfaces, and the support shafts 38a and 38b are rotatably
supported by the outer frame 26.
[0041] The control lever 32 is attached to a rotational shaft 40
rotatably provided between the sides of the inner frame 30 in the
direction which intersects the axial direction of the support
shafts 38a and 38b. The control lever 32 is supported by the inner
frame 30 so as to be able to move about a fulcrum along a first
direction X (back-and-forth direction).
[0042] The control lever unit 24 can also move about a fulcrum in a
second direction Y which intersects the first direction X at right
angles by means of the support shafts 38a and 38b.
[0043] A grip 41 is attached to the upper end of the control lever
32. A plunger 42 placed inside the control lever 32 is provided at
the lower end of the control lever 32 in a state in which the
plunger 42 is biased by a coil spring 44 inside the control lever
32 and projects from the lower end of the control lever 32.
[0044] The positioning rollers 34a and 34b are disposed at the
back-and-forth positions of the inner frame 30 in a state in which
the positioning rollers 34a and 34b are adjacent to each other so
as to be positioned on either side of the end position of the
plunger 42 in a state in which the control lever 32 stands
upright.
[0045] Therefore, the control lever 32 can be positioned at a first
displacement position A at which the control lever 32 is pushed
forward so that the plunger 42 at the end of the control lever 32
passes over the positioning roller 34a and is positioned on the
left of the positioning roller 34a, a second displacement position
B at which the control lever 32 is pulled backward so that the
plunger 42 at the end of the control lever 32 passes over the
positioning roller 34b and is positioned on the right of the
positioning roller 34b, and a neutral position C at which the
control lever 32 is made to stand upright so that the plunger 42 of
the control lever 32 is positioned between the positioning rollers
34a and 34b.
[0046] A gearshift feeling occurs when shifting the control lever
32 by causing the plunger 42 at the end of the control lever 32 to
be displaced so as to pass over the positioning roller 34a or 34b,
whereby an excellent operational feeling can be obtained.
[0047] Stopper rollers 46a and 46b for securing the control lever
32 when the control lever 32 is positioned at the first
displacement position A or the second displacement position B are
provided.
[0048] As shown in FIGS. 4A, 4B, 5A, and 5B, the lever position
detection sections 36a and 36b are disposed on either side of the
rotational shaft 40 with the control lever 32 interposed
therebetween.
[0049] The lever position detection sections 36a and 36b are formed
by detection switches. Flat abutment surfaces 48a and 48b are
formed by cutting the rotational shaft 40 corresponding to the
lever position detection sections 36a and 36b.
[0050] In the case where the control lever 32 is pushed forward,
the lever position detection section 36b is turned OFF as shown in
FIG. 4A, and the lever position detection section 36a is turned ON
as shown in FIG. 4B.
[0051] In the case where the control lever 32 is pulled backward,
the lever position detection section 36b is turned ON as shown in
FIG. 5A, and the lever position detection section 36a is turned OFF
as shown in FIG. 5B.
[0052] Therefore, the lever position detection sections 36a and 36b
can detect the state in which the control lever 32 is pushed
forward and the state in which the control lever 32 is pulled
backward.
[0053] The outer frame 26 is in the shape of a rectangular
parallelepiped which covers the control lever unit 24 in a state in
which the upper part of the control lever 32 projects upward. A
screw rubber spring 50 is attached to the outer side surface at a
position corresponding to the support shaft 38b. The screw rubber
spring 50 biases the control lever unit 24 toward the neutral
position through the support shaft 38b.
[0054] As shown in FIGS. 6 and 7, unit position detection sections
52a and 52b which detect the movement of the control lever unit 24
are provided in the outer frame 26 at positions facing either side
of the inner frame 30.
[0055] The unit position detection sections 52a and 52b are formed
by detection switches. The unit position detection section 52a is
turned ON and the unit position detection section 52b is turned OFF
when the control lever 32 is moved to the left as shown in FIG. 6,
and the unit position detection section 52a is turned OFF and the
unit position detection section 52b is turned ON when the control
lever 32 is moved to the right as shown in FIG. 7 to detect the
moving position.
[0056] The movement of the control lever 32 in the back-and-forth
direction and the right-and-left direction can be securely detected
by detecting displacement of the control lever 32 in the
back-and-forth direction by using the lever position detection
sections 36a and 36b and detecting displacement of the control
lever 32 in the right-and-left direction by using the unit position
detection sections 52a and 52b.
[0057] Since the lever position detection sections 36a and 36b are
incorporated into the control lever unit 24, the control lever unit
24 can be independently used in the case where it suffices that the
control lever 32 be moved only in the back-and-forth direction,
whereby the degree of generality can be increased.
[0058] The moving path control section 28 controls the moving path
of the control lever 32. In the present embodiment, as shown in
FIG. 2, the control lever 32 can be shifted in four stages by
attaching a moving path control plate 56 which includes a control
lever guide groove 54 in the shape of the letter H consisting of
two parallel back-and-forth direction grooves 54a extending in the
back-and-forth direction on the upper surface of the outer frame 26
and an intermediate coupling groove 54b which couples the
back-and-forth direction grooves 54a.
[0059] The control lever 32 can be stopped at a forward position or
a backward position in the back-and-forth direction groove 54a on
the right or left by using the moving path control section 28 by
moving the control lever 32 to the control lever guide groove 54 on
the right or left through the intermediate coupling groove 54b and
positioning the control lever 32 at the first displacement position
A or the second displacement position B using the back-and-forth
direction groove 54a.
[0060] When the control lever 32 in this state is returned to the
neutral position C, the control lever 32 moves to the position of
the intermediate coupling groove 54b and is automatically returned
to the neutral position by the biasing force applied by the screw
rubber spring 50, whereby a state close to an operational feeling
of an actual gearshift lever can be obtained.
[0061] Although not shown in the drawings, the moving path control
section 28 can be exchanged corresponding to the moving path of
various types of control levers 32.
[0062] In the case of obtaining the moving path of a six-speed
control lever instead of the four-speed control lever, it is
possible to deal with such a case without adding a change to the
internal structure by replacing the moving path control section 28
with a moving path control section in which three parallel
back-and-forth direction grooves extending in the back-and-forth
direction are coupled by an intermediate coupling groove.
[0063] The present invention is not limited to the above-described
embodiment. Various modifications and variations are possible
within the spirit and scope of the present invention.
[0064] In the above-described embodiment, the control lever device
is used for a driving game machine. However, the control lever
device may be employed for a driving simulator or the like insofar
as a plurality of multi-directional shift operations are
necessary.
[0065] In the above-described embodiment, the control lever can be
positioned at the first displacement position, the second
displacement position, and the neutral position between the first
displacement position and the second displacement position by using
two positioning rollers. However, the control lever may be
positioned only at the first displacement position and the second
displacement position by using one positioning roller.
[0066] In the above-described embodiment, a screw rubber spring is
used as the neutral position biasing section which biases the
control lever unit toward a neutral position. However, the control
lever unit may be biased toward a neutral position by disposing a
coil spring between the outer frame and the inner frame.
[0067] Two unit position detection sections are used in the
above-described embodiment. However, one of the unit position
detection sections may be omitted by setting the neutral position
of the control lever unit at one of the back-and-forth direction
grooves.
[0068] The lever position detection section and the unit position
detection section are formed by switches. However, the present
invention is not limited thereto. The lever position detection
section and the unit position detection section may be formed by a
rotary encoder, a photosensor, or the like.
